that the operation ot the device will be readily understood and in view of the simplicity and practical value that it will readily Acommend. itself to those skilled in the art.

Having thus described the invention what l claim is l. The combination with a seat post having a horizontal shank portieri, and a saddle having a front spring provided with a rearwardly extending and downwardly spaced bight portion, and rear side springs; ot a ble with the shank ot the seat post, a shank laterally aud longitudinally adjustable in the forward end oi the truss and having means ier connection 'with the bighr portion of the forward spring, and means at the rear end ci the seat :tor adjustable connectlie seat up and dowuat the rear.

2. A bicycle saddle truss and' seat post clamp comprising a casting oi' lf-shape having a longitudinal opening and a clamping member depending therefrom and provided with a longitudinal slot to receive a seat post shank, means or connecting the 'lorwardly extending portion oli a iront saddle brace, and an adjustable shank tor connecting the rear portion of the casting to a rear saddle spring.

3. A truss of the class described comprising a substantially Y-'shaped member having vertically extending and substantially extending belowA the bight portion ont the member tor detachable andA adjustable engagement with a seat post, said depending portion having a longitudinal opening, an apertured shank e2;-

tending through the forwardlyA extending ortion and engageable with the apertured shank, and a socket at the forward end of the shank, said socket having means at the forward end of the same for connection horizontally or vertically with the sadlle spring.

4. The combination with a seat post having a shank; of atruss having aclampdeending therefromv and adjustably connectible with the shank, a saddle having a torward 4spring, means :tor connecting the Y the iforward end oii`: the truss, and means ttor adjustably connecting the rear end ot the truss tothe rea-r side springs of the saddle.

5. The combination with 'a saddle having a" Yforward spring provided with a rearwardly extending-'loop and rear side springs, bolts suspended from said springs, cushioning springs mounted on the bolts, 4a truss having a forked rear 1oortion and provided at the rear ends thereof with spaced apertures 'tor adjustable connection with said bolts,

llO

largement provided with a central slot providing opposed resilient clamping jaws, said jaws having coacting recesses forming an opening to receive the post, a clamping bolt extending through the jaws to tighten the same on the post, said truss having a forwardly extending portion provided with a longitudinally extending opening, said forwardly extending portion having registering horizontal and vertical apertures therethrough, a shank having a series of openings in spaced relation therethrough to align with the vertical or horizontal apertures, said shank having a .forward enlargement providing a shoulder to limit the rearward displacement thereoil and provided with a flat socket for horizontal or vertical disposition to receive the loop of the saddle spring therein, and clamping means in the socket to secure the saddle sprinoin position.`

6. bicycle saddle truss and clamp comprising a casting having a shank portion and branching leg portions, the eX- tremities of the leg portions being disposed inwardly in parallel relation an-d extending vertically, said portions being each provided with a spaced series of openings and seat post an adjacent slot alongside thereof, a depending portion formed upon a casting and having means for engaging a seat post, the shank portion havinga longitudinal opening extending through the bight of the truss and opposed horizontally and vertically registering apertures adjacent the forward end thereof, a shank extending in said open ing, a securing means extending through ythe shank and apertures to hold the shank in .an adjusted position longitudinally or laterally and a clamping member at the forward end of the adjustable shank.

7. In a truss of the class described, a longitudinally bored. casting having a bottom clamp detachably engageable with a seat post, means at the rear ends of the casting for adjustable connection with a saddle to hold the same at any desired tilt, an eXtensible member engaged in the opening of the shank of the truss and provided with a flattened socket for receiving the f front spring of a bicycle saddle, said socket having opposed apertures and a clamping member engaged with the apertures to secure the spring in position.
